* | [PATCH] UML - fix utsname build breakageJeff Dike2006-07-15
| | | | | | | | | | | | | | | | | | | | | | | | Some -mm-only material leaked into a patch destined for mainline, and I didn't notice. This was the replacement of system_utsname with utsname() that's required by the uts namespace patch. This patch reverts those changes (which are correct in -mm) so that mainline UML builds again.

* | Don't allow chmod() on the /proc/<pid>/ filesLinus Torvalds2006-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This just turns off chmod() on the /proc/<pid>/ files, since there is no good reason to allow it, and had we disallowed it originally, the nasty /proc race exploit wouldn't have been possible. The other patches already fixed the problem chmod() could cause, so this is really just some final mop-up.. This particular version is based off a patch by Eugene and Marcel which had much better naming than my original equivalent one.

This will usually work fine until you hit something that uses the packet length or tail from the frag_list. Examples include esp_output and ip_fragment. Another problem caused by this is that you can end up with a linear packet with a frag_list attached. It is possible to get away with this if we audit everything to make sure that they always consult skb->len before going down onto frag_list. In fact we can do the samething for the paged part as well to avoid copying the data area of the skb. For now though, let's do the conservative fix and update frag_list.

* | | | [PATCH] remove set_wmb - arch removalSteven Rostedt2006-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | set_wmb should not be used in the kernel because it just confuses the code more and has no benefit. Since it is not currently used in the kernel this patch removes it so that new code does not include it. All archs define set_wmb(var, value) to do { var = value; wmb(); } while(0) except ia64 and sparc which use a mb() instead. But this is still moot since it is not used anyway.

* | | | [PATCH] Remove down_write() from taskstats code invoked on the exit() pathShailabh Nagar2006-07-15

If the oom-killer decides to kill tasks to satisfy the allocations,the exit of those tasks could block on the same semphore. The down_write() was only needed to allow removal of invalid listeners from the listener list. The patch converts the down_write to a down_read and defers the removal to a separate critical region. This ensures that even if the oom-killer is called, no other task's exit is blocked as it can still acquire another down_read. Thanks to Andrew Morton & Herbert Xu for pointing out the oom related pitfalls, and to Chandra Seetharaman for suggesting this fix instead of using something more complex like RCU.

* | | | [PATCH] per-task delay accounting taskstats interface: control exit data ↵Shailabh Nagar2006-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | through cpumasks On systems with a large number of cpus, with even a modest rate of tasks exiting per cpu, the volume of taskstats data sent on thread exit can overflow a userspace listener's buffers. One approach to avoiding overflow is to allow listeners to get data for a limited and specific set of cpus. By scaling the number of listeners and/or the cpus they monitor, userspace can handle the statistical data overload more gracefully. In this patch, each listener registers to listen to a specific set of cpus by specifying a cpumask. The interest is recorded per-cpu. When a task exits on a cpu, its taskstats data is unicast to each listener interested in that cpu. Thanks to Andrew Morton for pointing out the various scalability and general concerns of previous attempts and for suggesting this design.

Currently the taskstats interface allocates a structure, fills it in and calls netlink to send out per-pid and per-tgid stats regardless of whether a userspace listener for the data exists (netlink layer would check for that and avoid the multicast). As a result of this patch, the check for the no-listener case is performed early, avoiding the redundant allocation and filling up of the taskstats structures.

* | | | [PATCH] delay accounting taskstats interface send tgid onceShailabh Nagar2006-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Send per-tgid data only once during exit of a thread group instead of once with each member thread exit. Currently, when a thread exits, besides its per-tid data, the per-tgid data of its thread group is also sent out, if its thread group is non-empty. The per-tgid data sent consists of the sum of per-tid stats for all *remaining* threads of the thread group. This patch modifies this sending in two ways: - the per-tgid data is sent only when the last thread of a thread group exits. This cuts down heavily on the overhead of sending/receiving per-tgid data, especially when other exploiters of the taskstats interface aren't interested in per-tgid stats - the semantics of the per-tgid data sent are changed. Instead of being the sum of per-tid data for remaining threads, the value now sent is the true total accumalated statistics for all threads that are/were part of the thread group. The patch also addresses a minor issue where failure of one accounting subsystem to fill in the taskstats structure was causing the send of taskstats to not be sent at all. The patch has been tested for stability and run cerberus for over 4 hours on an SMP.

This patch creates the interface without populating the fields of the data that is sent to the user in response to a command or upon the exit of a task. Each accounting package interested in using taskstats has to provide an additional patch to add its stats to the common structure.

* | | | [PATCH] Fix security check for joint context= and fscontext= mount optionsEric Paris2006-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After some discussion on the actual meaning of the filesystem class security check in try context mount it was determined that the checks for the context= mount options were not correct if fscontext mount option had already been used. When labeling the superblock we should be checking relabel_from and relabel_to. But if the superblock has already been labeled (with fscontext) then context= is actually labeling the inodes, and so we should be checking relabel_from and associate. This patch fixes which checks are called depending on the mount options.

Fix this by making the spinlock_release() in context_switch() dependent on !__ARCH_WANT_UNLOCKED_CTXSW. (Reported by Ralf Baechle on MIPS, which has __ARCH_WANT_UNLOCKED_CTXSW. This fixes a lockdep-internal BUG message on such platforms.)
